These regulations set certification requirements for recycling and recovery equipment, as well as for technicians and refrigerant reclaimers. The sale of refrigerant is restricted to certified technicians. Persons performing service or disposing of air conditioners or refrigeration equipment must certify to EPA that they have acquired the proper equipment and are complying with these regulations. Finally, these rules require substantial leaks from air conditioners and/or refrigeration equipment be repaired, and establish requirements to ensure equipment entering the waste stream with a charge still intact are properly evacuated and disposed of. Venting ProhibitionThe purposeful venting of refrigerant during the maintenance, repair or disposal of air conditioners and refrigeration equipment is strictly prohibited. Only four specific types of releases are permitted.
Evacuation RequirementsIf opening the equipment, technicians are required to evacuate refrigerant to established vacuum levels. The required levels depend on when the equipment being used was manufactured and what type of refrigerant is being evacuated. See Table 1 below. Technicians repairing small appliances (window air conditioners, household refrigerators and water coolers) must recover 80% of the refrigerant if using evacuation equipment manufactured before November 15, 1993, or the compressor in the appliance is not operating. Technicians repairing small appliances must recover 90% of the refrigerant if using evacuation equipment manufactured on or after November 15, 1993, and the compressor in the appliance is operating.

Equipment CertificationIf evacuation equipment was manufactured on or after November 15, 1993, it must have been certified by an EPA-approved equipment testing organization such as Underwriters Laboratories (UL) or the Air Conditioning and Refrigeration Institute (ARI). Certified equipment will have the following printed on it: “This equipment has been certified by ARI/UL to meet EPA’s minimum requirements for recycling and/or recovery equipment intended for use with (appropriate category of appliance inserted)”. EPA requires that persons performing maintenance or disposing of refrigeration equipment acquire the proper equipment and notify the appropriate EPA Regional Office of the use of such equipment as well as certify that the applicable requirements are being met. This certification must be signed by the owner/operator. An example certification form is included. Refrigerant LeaksOwners of equipment with charges greater than 50 pounds are required to repair refrigerant leaks from such equipment when all leaks would together result in the loss or a certain percentage of total refrigerant over one year.
More detailed requirements for refrigerant leak repair exist depending on the use/retirement plan for the equipment, if shut down is required to make repairs, etc. Technician CertificationA technician certification program exists for those performing maintenance, service or repair. A technician is defined as a person attaching/detaching hoses and gauges to and from appliances to measure pressure within the appliance; adding refrigerant to or removing refrigerant from an appliance; or any other activity that may violate the integrity of the small appliance. Types of Certification
Certification is obtained by passing an EPA-approved test given by an EPA-approved certifying organization. The EPA’s Ozone Protection Hotline (800-296-1996) or IWRC may be contacted for a list of EPA-approved certifying organizations. Technician certification is not required for those removing refrigerant from appliances in the waste stream that could reasonably release refrigerant into the atmosphere. Refrigerant SalesThe sale of refrigerant in any size container is restricted to certified technicians as described above or certified according to the MVAC regulations. This sales restriction includes refrigerant in bulk containers (cylinders/drums) and pre-charged parts. It does not include refrigerant contained in refrigerators/air conditioners with fully assembled refrigerant circuits. Nor does it include pure HFC, CFC or HCFC refrigerants not intended for use as a refrigerant. Refrigerant Equipment DisposalEquipment that typically enters the waste stream with an intact refrigerant charge (MVACs, household refrigerators and freezers, room air conditioners, etc) is subject to special safe disposal requirements. The final person in the disposal chain is responsible for ensuring that refrigerant is recovered from all equipment before the final disposal of the equipment. Persons “upstream” may remove and properly dispose of refrigerant before the equipment reaches the final disposal phase. They should provide documentation of its removal to the final person in the waste stream. The same performance standards are required for equipment used to recover refrigerant at the final disposal phase, however such equipment does not need to be tested by a laboratory. This allows for self-built equipment, as long as it meets the following performance standards.
Refrigerant DisposalIf refrigerants are recycled or reclaimed, they are not considered hazardous waste. In addition, used oils contaminated with CFCs are not hazardous waste if the oils are not mixed with other waste, are subjected to CFC recycling or reclamation, and are not mixed with used oils from other sources.
Type I systems are factory charged. This means technicians do not need to charge the appliance. All the refrigerant needed is already contained inside the appliance. Type I appliances can be used straight out of the box. Question #4: Hermetically sealed systems are systems that cannot lose refrigerant. What type of appliances are technicians certified to charge and open after passing the Type I Examination A?What type of appliances are technicians certified to charge and open after passing the Type 1 examination? Appliances containing 5 pounds or less of refrigerant that have been hermetically sealed and charged at the factory. Which of the following are included in EPA’s definition of a small appliance?The EPA definition of a small appliance includes; products manufactured, fully charged, and hermetically sealed in a factory containing five pounds or less of refrigerant. Split-systems may not be serviced by Type I technicians. What type of certification is required for persons recovering CFCs HCFCs HFCS during maintenance service or repair of small appliances?Technicians must pass an EPA-approved test to earn Section 608 technician certification. Which best describes the definition of Type 1 small appliance as defined by the EPA?Which best describes the definition of Type I Small Appliance, as defined by EPA? Systems manufactured, charged and hermetically sealed with( 5) pounds of less of refrigerant. You just studied 143 terms! 1/143. What is the definition of a Type 2 appliance?As weve defined, EPA Type II appliances are high-pressure appliances. A high-pressure appliance is any appliance that requires high system pressures to convert refrigerant from a gas to a liquid. What is a Type 3 appliance?Type 3 appliances have a pressure lower than atmospheric pressure. So they are known to work in a vacuum. A vacuum cleaner is the best example of a device that works in a vacuum. Recall that any matter flows from a high to low pressure. A vacuum cleaner creates a low-pressure (vacuum) that sucks all the air and dirt. What type of appliances are technicians certified to charge and open after passing the Type 1 exam?What type of appliances are technicians certified to charge and open after passing the Type 1 examination? Appliances containing 5 pounds or less of refrigerant that have been hermetically sealed and charged at the factory. What are Type 1 appliances?Type I appliances are hermetically sealed. This means that internal components are sealed from outside elements and airtight.
